> Key: SPARK-17686
> URL: https://issues.apache.org/jira/browse/SPARK-17686
> Project: Spark
> Issue Type: Improvement
> Components: Spark Submit
> Reporter: Saisai Shao
> Priority: Minor
>
> Currently we have a use case that needs to upload different jars to Spark
> according to scala version. For now only after launching Spark application
> can we know which version of Scala it depends on. It makes hard for some
> services which needs to support different Scala + Spark versions to pick the
> right jars.
> So here propose to print out Scala version according to Spark version in
> "spark-submit --version", so that user could leverage this output to make the
> choice without needing to launching application.
